The modular housing is for DIN-rail mounting with IP20 protection degree.The device, in its basic configuration, is able to measure the electrical motor variables (current, voltage, harmonic distortion, etc), tocontrol the thermal image of the motor, and also its load, operational status (start- stop, star-delta starting, 2 speeds, alarm set-point and other functions adjustable by the user), motor temperature and includes an event data- logger.The current measurement is carried out by means of 3 external current transformers, or by pass- through holes up to 5 A. Being provided with a serialcommunication module, it is possible to gather all the relevant instantaneous values and transmit them to a host control system for data collection and process control. Profibus and Modbus TCP protocols are available for a high connectivity to the most used fieldbus systems. Through the optional remote display (for panel mounting) it is possible to see the instantaneous values andstatus and also to modify the set-points and the values of other parameters. The whole programming of the unit is to be performed via configuration software. Additional optional modules allow the collection of additional PTC and PT100 values for coils and bearing temperature control, and additional input/outputs are used for some local on- board logic functions.Type SelectionDMPUC-PRB Main module + Profibus.DMPUC-MBT Main module + ModbusTCP/IP.DMPUC-05 Currents and voltagesmodule (pass-through holes).DMPUC-65 Currents and voltages module.DMPUC-R2 I/O module.DMPUC-EL Earth leakage current module1 Specifications are subject to change without notice.
